Exploring the relationship between leaf water potential, defoliation, and grape berry physical properties of Merlot (Vitis vinifera L.) grapevine

چکیده
The aim of this study was to examine the impact leaf water potential and defoliation treatments on physical properties grape berries. research conducted over two consecutive years (2019-2020) using ‘Merlot’/41B graft combination grapevines grown in Chateau Kalpak vineyards located Tekirdağ, Şarköy. experiment involved four distinct stress levels (S0, S1, S2, S3), which were determined based measurements. These subjected different irrigation levels. Additionally, applied, including Control (C), Full Window (FW), Right (RW), Left (LW). results showed that effects berry statistically insignificant. However, second year study, FW treatment observed have led changes desired direction for grapevines. This likely due cumulative decrease reserves caused by reduced precipitation multiple years, making more prominent. Moreover, found both current past vegetation period conditions influence vine production year, potentials (Ψleaf), Finally, data revealed weight % dry increased with higher

Influence of deficit irrigation and kaolin particle film on grape composition and volatile compounds in Merlot grape (Vitis vinifera L.).
The effect of deficit irrigation and a kaolin-based, foliar reflectant particle film (PF) on grape composition and volatile compounds in Merlot grapes was investigated over two growing seasons in semi-arid, south-western Idaho. Vines were provided with differential amounts of water based on their estimated crop evapotranspiration (ET(c)) throughout berry development, and particle film was appli...
متن کاملPotassium in the Grape (Vitis vinifera L.) Berry: Transport and Function
K+ is the most abundant cation in the grape berry. Here we focus on the most recent information in the long distance transport and partitioning of K+ within the grapevine and postulate on the potential role of K+ in berry sugar accumulation, berry water relations, cellular growth, disease resistance, abiotic stress tolerance and mitigating senescence. By integrating information from several dif...
متن کاملSugars and flowering in the grapevine (Vitis vinifera L.).
Sugars play an important role in grapevine flowering. This complex process from inflorescence initiation to fruit maturity takes two growing seasons. Currently, most of the available data concern the involvement of sugars as energy sources during the formation of reproductive structures from initiation of inflorescences during the summer of the first year, until flower opening during the follow...
متن کاملCarbohydrate reserves in grapevine (Vitis vinifera L. 'Chasselas'): the influence of the leaf to fruit ratio
Seasonal dynamics of total non-structural carbohydrates (TNC) in relation to the leaf-fruit ratio were measured over five years at different grapevine phenological stages in oneand two-year-old canes, trunks and roots of the cultivar 'Chasselas' (Vitis vinifera L.). Carbohydrates were mainly stored as starch in different parts of the grapevine during the growing season. Soluble carbohydrates re...
متن کاملUnderstanding Differential Responses of Grapevine (Vitis vinifera L.) Leaf and Fruit to Water Stress and Recovery Following Re-Watering
Among all fruit crops of horticultural importance, grapevines (Vitis vinifera L.) stand out as the most drought tolerant crop species whose tolerance is credited to their proficiency to recover from water stress in both the natural and vineyard growing conditions. However, information on the recovery responses is relatively scant. Studies were conducted to address this issue using potted vines ...
